Works of the old man :
About 50,000 years ago, there was a marked increase in the diversity of artifacts. For
the first time in Africa, bone artifacts and the first art appear in the archeological record. The first evidence of human fishing is also noted, from artifacts in places such as Blombos cave in South Africa. Firstly among the artifacts of Africa, archeologists found they could differentiate and classify those of less than 50,000 years into many different categories, such as projectile points, engraving tools, knife blades, and drilling and piercing tools. These new stone-tool types have been described as being distinctly differentiated from each other, as if each tool had a specific purpose. Three thousand to 4,000 years later, this tool technology spread with people migrating to Europe. The new technology generated a population explosion of modern humans which is believed to have led to the extinction of the Neanderthals. The invaders, commonly referred to as the Cro-Magnons, left many sophisticated stone tools, carved and engraved pieces on bone, ivory and antler, cave paintings and Venus figurines.
This shift from Middle to Upper Paleolithic is called the Upper Paleolithic Revolution. The Neanderthals continued to use Mousterian stone tool technology, but were probably extinct by about 22,000 BCE. This period has the earliest remains of organized settlements in the form of campsites, some with storage pits. These were often located in narrow valley bottoms, possibly to make hunting of passing herds of animals easier. Some sites may have been occupied year round, though more generally, they seem to have been used seasonally; peoples moved between them to exploit different food sources at different times of the year. Hunting was important, and caribou/wild reindeer "may well be the species of single greatest importance in the entire anthropological literature on hunting.
Technological advances included significant developments in flint tool manufacturing, with industries based on fine blades rather than simpler and shorter flakes. Burins and racloirs were used to work bone, antler and hides. Advanced darts and harpoons also appear in this period, along with the fish hook, the oil lamp, rope, and the eyed needle.
Artistic work blossomed, with Venus figurines, cave painting, carvings and engravings on bone or ivory (such as the Swimming Reindeer), petroglyphs and exotic raw materials found far from their sources, which suggests emergent trading links. More complex social groupings emerged, supported by more varied and reliable food sources and specialized tool types. This probably contributed to increasing group identification or ethnicity. These group identities produced distinctive symbols and rituals which are an important part of modern human behavior.
